Using X-Ray Microscopy to Study the Inner-Workings of Batteries and Fuel Cells

Microscopy is being used by the Electrochemical Innovation Laboratory (EIL) at the University College London (UCL) to study the inner-workings of fuel cells and batteries. ZEISS Xradia 810 Ultra allows them to study the evolution of microstructure as small as 50 nm resolution, revealing the fine details of Li-ion batteries in 3D.

The research team at UCL is able to obtain multi-scale results, relating large features in the package to the complex pore pathways within the separators and electrode layers by combining the sub-micron resolution and high penetrating power of ZEISS Xradia 520 Versa.

With ZEISS Xradia 810 Ultra we can accomplish non-destructive 3D imaging with spatial resolution comparable to the synchrotron sources, achieving important results in a range of disciplines including chemical engineering, materials sciences and earth sciences.

As X-rays penetrate most objects, there is no need to “slice” the specimens for X-ray microscopy before or during imaging. As a result, these investigations can be extended into the 4th dimension, to explore the evolution of 3D microstructure with time.
